圆形磁耦合截面构建的新型时栅位移传感器
A Novel Time-Grating Displacement Sensor Based onthe Circular Magnetic Coupling Cross Section
摘要
Abstract
There exist some problems on the current magnetic-field time-grating displacement sensor,such as the unequal interval of tooth and slot,the inconsistent parameters of coils and the poor quality of electrical signals formed by the coupling magnetic field.To solve the above problems,a new method to design sensor is presented that it uses the ferromagnetic material with a circular cross section to replace the traditional ferromagnetic material with rectangular section to build the coupling magnetic field.The method adapts the standard parts as the basic array permeability units,supplemented by customized precision winding to design a new variable reluctance time grating displacement sensor.Firstly,the feasibility simulation of the theoretical model is verified by the finite element software ANSYS Maxwell.Then,the error curve of error range within±1.3 arc-sec is obtained by the precision experiment.The simulation and practical experiments verify the feasibility of new sensors.The application of this method evade the mechanical processing form of slotting by traditional linear cutting and wiring,greatly improve the quality of output signal and production efficiency,at the same time is good to promoting the transition progress of the time grating sensor.关键词
